QUINCY, ILLINOIS, A COR-EORATION OF LUBRECATGR.

Application iiled February 17, 1926. Serial ITo. 88,866.

The present invention relates to that type of lubricator which is placed in a hose line, the lubricant being introduced into the fluid passing through such line. l.7Vl`fiile it is particularly intended and adapted for use in iieXible hose lines, it of course is not limited to such use.

In devices of this kind it has heretofore been essential that the lubricator be maintained in a predetermined position in order that the lubricant will flow from the reservoir into the hose line, because if turned or tipped over, the channel through which the lubricant enters the fluid passageway may have its inlet end above the level of the lubricant and the flow of lubricant is thus stopped. inasmuch as the hose lines are apt to be moved during the operation of the instrument or apparatus connected to it, there is consider-v able opportunity of the lubricator being thus turned or tilted.

One of the primary objects oi the invention is to provide a simple lubricator of an effective character, which is operative, irrespective of the position it may take. Another and important object is to provide a lubricator by which the reservoir may be substantially i'illed and still be operative. Still another object is to provide novel means of an eiiective character by which the amount of lubricant delivered into the motive liuid can be varied.

In the accompanying drawings Figure 1 is a longitudinal sectional view through the preferred embodiment of the invention, v

Figure 2 is a vertical cross sectional view on the line 2-2 of Figure 1.

A casing of general ovoidal character is employed, comprising Sections 3 and 4 that are threaded together, as shown at 5. rlhe ends of the casing have coupling nipples 6, to which the hose may be attached in any wellknown manner. The ends also have inwardly extending tubular nipples 7, the bores 8 of which have reduced inner portions 9. Bearing sockets 10 are formed in the inner ends of the nipples.

A sleeve 11 has its ends journaled in the sockets 10 and bridges the space between the inner ends of the nipples 7, the bore 12 of this sleeve forming with the bores 8 and 9 a Huid passageway longitudinally through the casing. The interior of the casing around said pgssageway constitutes a lubricant reservoir The central portion or" the bore 12 of the sleeve is enlarged as shown at 14. @ne side the sleeve is provided with a pendulum mass 15, and on the opposite side with an upstanding tubular portion 16. Said portion 16 and the pendulum mass 15 have a stem chamber 17 that is disposed transversely of the bore 12 14. In this chamber is rotatably mounted a stem 18, the lower end of which is seated on a coiled spring 19, the stem being held in place by a transverse pin 20 engaged in an annular groove 21 formed in the stem.

A lubricant-conducting conduit 22 has a lower inlet end 23 formed in the bottom or'l the pendulum mass and extends upwardly where it is in communication with an annular groove 24 formed in the upper end of the stem 18. The inlet end 23 is preferably covered by a screen 25. The stem furthermore has a longitudinal downwardly extending bore or channel 26 in communication with the groove 24, and said channel has transverse outlet ports 27 which open through opposite sides of the stem 18 midway of the bore 1214. rlhis stem also has at right angles to the ports 2 7, fluid inlet ports 28 that are in communication with a downwardly extending channel 29 that opens through the lower end ot the stem into the lower end of the bere or chamber 17. From this lower end a conduit 30 leads upwardly and opens into the upper end of the lubricant reservoir 13. I

The casing 3 4 is provided with an opening 31 with which the upper end of the stem 18 is adapted to aline, and said end may be provided with means for engagement by a tool to turn the stem. Thus, as shown said end of the stem has sockets 32 for the reception of the prongs of a turning tool. The upper end of the bore 26 is also preferably closed by a plug 33. The opening 31 is noimally closed by a threaded plug 34.

The section 3 constitutes the main body section of the casing and its open end is obviously large enough to permit the pendulum niember being introduced therethrough, the section 4 constituting not only the end wall but a closure for the open end of the body section.

With this construction, it will be evident that the motive fluid to be supplied to the apparatus and conveyed by a hose line passes through the nipples 8 and bore of the sleeve 11. It lubricant is in the reservoir 13 and the parts are as shown in the drawing, a portion of the motive lluid will pass through the ports 28 and a part will be deflected, as indicated by the arrows, downwardly through the channel 29 and thence upwardly through the conduit 30 into the upper part of the reserJ voir, placing` pressure on the lubricant in said reservoir. As a consequence lubricant will rise through the conduit 22, and thence passing downward to the channel 26, will escape through the ports 27 and be caught by the passing 'fluid and carried away with it. By turning the stein thepressure in the lubricant reservoir can be varied, thus altering the amount of lubricant delivered.

Vith this structure it will be evident that irrespective of how the casing 3 may turn or Y roll the pendulum mass l5 will maintain the motive fluid supply and lubricant delivery means always in a vertical position, thus insuring that the inlet 23 of the lubricant conduit will be submerged in the lubricant, while the aii delivery conduit 30 will be above the level of the saine. Furthermore by the arrangement disclosed, it will be evident that the reservoir 13 may be nearly lilled with liquid without overflowing into the conduit 30.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details ot construction may be resorted to without departing from the spirit or sacrificing any ot' the advantages of the invention.
